摘要:

蛋白质中的半胱氨酸对维持和调控细胞内的氧化还原平衡起着重要作用,同时它们也是多种蛋白质的功能活性位点,参与诸多生理过程。此外,蛋白质中的半胱氨酸上所发生的一系列翻译后修饰也扩展了蛋白质功能的多样性。随着化学蛋白质组学的发展,基于活性的蛋白表达谱(Activity-based protein profiling,ABPP)分析技术在探究蛋白质半胱氨酸及其翻译后修饰方面取得了很多重要的研究成果。本文简要介绍了用于蛋白质半胱氨酸的活性蛋白表达谱分析方法,讨论了针对蛋白质半胱氨酸及其翻译后修饰的蛋白质组学领域的最新研究,并对该领域的未来发展趋势进行了展望。

Abstract:

Proteomic cysteines play important roles in maintaining and regulating redox homeostasis in cells; they also act as functional active site in many proteins and participate in many physiological processes. In addition, post-translationally modifying proteomic cysteines also extends protein functional diversity. The development of chemical proteomics and activity-based protein profiling (ABPP) has led to many important improvements that enable cysteines and their post-translational modifications to be explored. In this paper, we briefly introduce ABPP methods for the proteome-wide profiling of cysteines, present the latest proteomics research into protein-based cysteines and their post-translational modifications, and discuss future developmental trends in this field.
